# RD Sharma Class 10 Chapter 12 (Some Applications of Trigonometry) Solutions

ShareTrigonometry finds its applications in astronomy, construction of maps, and navigation. There are three important terminologies of **RD Sharma Class 10 Chapter-12**, which are the line of sight, the angle of elevation, and the angle of depression.

As you have already studied the topic ‘trigonometric ratios’ in Chapter-5, you can find out the distance between two distant objects using these ratios. Alternatively, you can also find out the length or height of an object.

With a total of 72 questions present in the first exercise itself, you can entirely depend on RD Sharma Solutions for strengthening all your concepts. ** **

**Important Terminologies of Applications of Trigonometry Class 10 | RD Sharma**

- Line of Sight: Line drawn between the eye of an observer to the point in the object viewed by the observer.

- Angle of Elevation: The angle formed between the line of sight and the horizontal when the point under consideration is above the horizontal level.

- Angle of Depression: The angle formed between the line of sight and the horizontal when the point under consideration is below the horizontal level.

**Concepts in RD Sharma Class 10 Chapter-12**

To solve a particular question, you will first assess the given values such as the angle of elevation or angle of depression or distance between the object and the observer.

RD Sharma Class 10 Chapter-12 consists of the following topics.

- Introduction
